Let’s talk about crossovers. Specifically, when Izuku and Katsuki get thrown into other universes, the theme I notice most is power systems clashing. It’s rarely about them just visiting Hogwarts and casting spells; it’s about how their Quirks—One For All and Explosion—interact with chakra, ninjutsu, ki, or magic. A story might have Deku’s analysis skills trying to decode jujutsu from 'Jujutsu Kaisen,' while Bakugo’s raw power gets recalibrated against curses.
What’s compelling is how their dynamic gets reframed. In a 'Demon Slayer' setting, their rivalry might center on breathing techniques versus Quirk mastery, with Deku’s empathy clashing with Bakugo’s aggression toward demons. The 'foils to each other' theme gets amplified when external rules challenge their core beliefs.
I’ve read a few where they’re inserted into 'My Hero Academia' but in a 'Marvel' or 'DC' universe—then it becomes about hero societies contrasting. Does their world’s licensed hero system hold up against vigilantism or cosmic threats? The crossover often highlights how their partnership, strained as it is, adapts under totally new pressures. Their growth isn’t just personal; it’s systemic.
Sometimes the theme veers into deconstruction: what if their world’s logic doesn’t apply? That’s where the real tension lies, not just in fights but in ideology. Bakugo’s win-at-all-costs mentality might be celebrated in one universe and condemned in another, forcing Deku to defend him. That protective angle is a surprisingly common thread.

The most dominant theme I've noticed is this sense of legacy, of carrying the torch. It's everywhere, and it can be so satisfying. You get stories where All Might is a lot more hands-on in training, maybe teaching Izuku some of the tactical stuff he learned over the years that didn't make it into the standard curriculum. The emotional core is always that father-son dynamic, with All Might grappling with his own mortality and Izuku terrified of not being enough.
Another huge one is fix-its, especially for 'that' moment after Kamino. So many fics explore All Might surviving longer, or Izuku learning One For All's secrets earlier, which lets them actually have a proper mentor-student relationship without the looming deadline. It's a massive wish-fulfillment niche. Then you've got the AUs where All Might adopts him, which just cranks the found family theme to eleven.
Less common, but I've seen a few that really dig into the horror of One For All's stockpile, the idea of all those past users whispering in Izuku's head, with All Might as the only one who can remotely understand. Those can get dark, but they're fascinating.

I've spent more hours than I'd care to admit in the 'My Hero Academia' fic trenches, and Deku-centric selfcest fics always have this fascinating undercurrent. The dominant theme is definitely intense self-reflection—what would I say to myself? Would I like me? That kind of thing. It's less romantic and more psychological, exploring his own doubts and admiration from a meta perspective. You'll see a lot of 'two halves of a whole' imagery, where one Izuku represents his heroic, self-sacrificing side and the other embodies the quirkless kid he used to be.
Another huge one is the theme of validation. It's Izuku giving himself the acceptance and belief All Might eventually gave him, but from the inside out. The fics often use the pairing to craft these intricate internal monologues disguised as dialogue, which can be surprisingly healing to read. They also play with the loneliness of carrying One For All's secret; having another version of yourself means finally having someone who understands everything without explanation.
The angst potential is off the charts, naturally. Guilt over past failures, fear for the future, the weight of a legacy—it all gets doubled when there are two of him to worry about each other. But weirdly, the fluff can be super soft too. It's the ultimate comfort in a universe where he's constantly pushing himself, a narrative where Izuku Midoriya finally gets to be his own supportive friend.

I've wandered through the tag for a while now, and honestly? The 'hero training gone wrong' premise is everywhere, but it's the variants that stick. Lots of fics play with the idea of a parallel universe Deku showing up—either a version who never got One For All or one who went completely villain. The tension comes from our Deku confronting a reflection of his own potential failures.
Then there's the internal split fics, where some quirk accident or psychic attack literally divides him into multiple personalities or physical copies. Those get messy fast, but the best ones use it to explore his self-sacrificing nature from an outside perspective. Like, one Deku seeing another constantly break his bones and finally understanding how terrifying that looks to everyone else. It's less about romance and more about intense self-analysis through a surreal lens.
A smaller subset I keep clicking on are the time-loop stories, where he's the only one aware of the reset. Watching him slowly build a rapport with his past self, trying to guide a more naive version without breaking everything... that's where the real character study happens. The ship tag feels almost incidental in those, just a framework for the introspection.
